In course of two-field experiments in the conditions of the Republic of Belarus there was studied the influence of organic fertilizers received at the output of biogas engines on productivity of green mass of maize (Zea mays). There was given comparative characteristic of efficiency of application of equivalent doses of organic fertilizers obtained at the output of biogas engines, chicken manure, cattle manure and mineral fertilizers. In course of the study there was analysed influence of fertilizers on yielding capacity of maize green mass of Delfin hybrid and Polesskij 212 hybrid. There was studied a balance of nutritive elements in the process of growing of maize hybrids for green mass. Research results showed that 1 ton of fertilizer on the basis of chicken manure provided 502-600 kg of maize green mass yield; 1 ton of fertilizers on the basis of swine manure – 239-287 kg of green mass. It is shown, that equivalent doses on nitrogen of the mineral fertilizers, traditional organic fertilizers and organic fertilizers received at the output of biogas-plant are characterized by identical agronomical efficiency.
